The cheelfllewll rrfrebliberwiided f 90 with an inverted U-shaped piece 17 of felt or other elastic material adapted to receive the upper edge of the glass 18 of the window. It will thus readily be understood that the ventilator is positioned at the top of the window opening, with the curved member 16 Within the car and the member 15 projecting outwardly and downwardly over the window. Secured within the tubular member l5 is a central baiile 19, and the shorter baliles 20, one on each side of baille 19. The ends oi the member aie closed adjacent to the plane of the window by the plates or batiles 21. It will be noted that the plates 21 extend out- 15 wardly a less distance thanxbaflies 20.

Secured in any desired manner between the frame members 13 and 14, and extending the length of the ventilator is a strip 22 of fine mesh screen to prevent the passage into Y zo the car of particles of dirt in the atmosphere.

The curved member 16 is provided with a plurality of series of elongated slots 23, shown on each of the figures of the drawings.

Snugly fitting within the curved member 2%"- 16 are the similar curved damper members 24, having therein slots 25, like the slots 23 in member 16. Two of the damper members 24 are provided, one for each end of the member 16. The ends of the members 24 are received ab* by the channels or grooves 26 and 27, and are arranged for upward and downward movement, as seen in Fig. 1 of the drawings. The member 16 is provided with the slots 28, through which extend the reduced portions si of the handles or knobs 29, the inner ends of said handles being fixed to the plates or dampers 24, respectively. The damper 24 is shorter than member 16, by the width of one of the slots 23. Therefore, it readily maybe 46T' seen that when one of the dampers 24 is in its uppermost position, the slots 23 will be open, and when a damper 24 is in its lowermost position, its solidL portions will overlie the slots 23. It is, of course, obvious that the El slots 23 may beclosed to any degree desired by adjusting the dampers 24.

If desire the ventilator may be provided with an extensible visor, as'shown in Fig.

i, 1. This device comprises a` plate or sheet 30 sof 'rigid material adjustably secured 'to the lower surface of the member 15. The plate 30 may be vprovided with slots 31, through which extend the lugs 32, the inner ends ofV which are riveted into the member 15. The

plate 31 is also providedv with a 4slot 33,

through which extends the setV screw 34, the

inner end of which is screw threaded into member 15. Set screw 34 may be used to i maintain the extensible visorV 30 inits ad- 00"`juste'cl position.

In operation, when the vehicle is in motion, air will be received in the forward end of the member 15.. Partv of it will encounter the aforwardbaile 20 and central baffle 19. and `willbe forced into the vehicle through the screen 22 and slots 23, assuming the corresponding damper is in open position. The balance of the air entering the member 15 will be placed under compression, and in rushing past the central baille 19, and out the rear end of the member 15, will have an ejector action and create a vacuum in the rear half of the ventilator, causing the air to be exhausted from the vehicle through the slots 23 in the rear half of member 16. The dampers 24 permit the amount of air admitted or exhausted from the vehicle to be controlled as desired. As the air is forcibly admitted at one end of the ventilator and exhausted from the other, the air in the vehicle is put in rapid circulation, and any `foul air or smoke is quickly re- Vmoved. The plates 21, at the ends of the radiator, act to deflect rain, snow and the larger particles of dirt inthe atmosphere downwardly into the lower part of member 15,

from whence it may readily pass out of the opposite end of member 15.

The device above described has, not only all the advantages of the ventilator disclosed in applicants patent above referred to, but in addition provides a visor or awning for the window.

lhile in the drawings and above description but one form oi' the device has been dis-v closed, it is to be understood that modifications in the form, relative size and arrangement of the parts are contemplated.' The invention, therefore, should be limited only by the scope of the claims.

Having thus described the invention, what I' claim is new and desire to secure by Letters Patent of the United States is:

1. In a ventilator for closed vehicles, a frame having an opening therethrough, meansfor securing said frame within a window opening of the vehicle, an elongated V- shaped member extending outwardly and downwardly from said frame, means securing the edges of said V-shaped member to said frame on opposite sides of said opening,
